For basic monitoring items, I get the following error - CPULoad (Return code of 127 is out of bounds - plugin may be missing) Disk [/x] (Return code of 127 is out of bounds - plugin may be missing) Process (Return code of 127 is out of bounds - plugin may be missing) However ping checks ok. What am I missing here ? Is there any error log for basic plugins ? Thanks Sam </BODY> </HTML>
